Ravenous Crypt

When tomb robbers loot the dead, sometimes the resting places of those victims animate to avenge them. This happens most frequently when the entombed person was a particularly greedy, gluttonous, or vindictive individual in life. Other ravenous crypts arise spontaneously in places where energy from the Void flows freely into other planes.

Boneyard Guardians

Ravenous crypts are occasionally encountered in the Boneyard, roaming that vast necropolis like packs of hungry dogs, although they quickly come to heel while in Pharasma's presence. This behavior has led some scholars to posit that the constructs are created at the behest—or at least with the blessing—of the Lady of Graves. Magrim, the demigod of the dwarven afterlife, is also believed to have some connection to ravenous crypts, as suggested by the fact the pediments of many crypts are carved with the scowling visages of dwarven elders.
